I don't like the idea or raising the age, but i think in practice, it would be a good idea.
A lot is said about growing bodies, and risk of injury, etc. But little about how much of a choice in the matter the skaters has.
Much of my feeling is sadly inspired by this quote from Alysa's dad

"I felt Alysa needed more intensity in her training and the coaches and I were not on the same page as to how the training should be"
Sure daddy is paying the bills, but i feel like at this level (of risk and otherwise) the skater should have a lot of say in "intensity" as it is their body. I now have to ask if Alysa's quads are by choice.
So the issue i am starting to have is, one of agency when you are dealing with children. It is one thing for an adult to think it is worth it to risk life long hip issues for an Olympic medal, it is another for a parent to make that choice for them. And it is not always easy or even possible to say no to mom/dad.
This is not anything new, and should not be seen as a dig at Arthur Liu, just this was the light-bulb for me. I remember Jenny Kirk talking about her mom making her skate with an injured hip... and that likely was under 6.0, Sadly this sport (and others) does not always have the best track record of looking out for kids. So maybe we need to accept that fact and move in a direction that at least means it is legal adults making these decisions for themselves about their own bodies and future.
And as some will say it, yes some skaters are young and think they are invincible and will push too much too soon as they don't fully understand the idea of chronic pain. Yes adults need to temper that. But take the Olympics away, and you are making that job easier.
So yes, I do think i want to raise the age, because i want people to be able to legally consent to competing on this level with all that that entails. In an ideal world, this would not be the case, but sadly i think we have some growing to do in order to get there.
